cooling devices jured by the steam generated by the process.

of permanent hair waving.

The objects of the present invention are to provide a suitable devicewhereby a current of air is released in close proximity to.

the scalp, thereby cooling the same and blowing away steam that may haveescaped from the curling apparatus.

Other objects of the invention are to provide a single distributorhaving one end adapted to be detachably connected to a suitable airblower, such as a hair drier, and having its opposite end closed andprovided with a plurality of flexible tubular extensions or ductscommunicating with and leading from said distributor. The free ends ofsaid extensions are adapted to be attached in positions adjacent to thescalp of the person whose hair is being treated so as to deliverthereagainst a current of air forced from said distributor by said airsupply means.

Further objects of the invention are to provide each free end of suchtubular exten sion with a nozzle and means for detachably attaching saidnozzle in position adjacent to the scalp and the curling rod.

Additional objects of the invention are to provide an apparatus of theclass described operate, can be readily attached to and detached fromposition and which can be used with any existing type of permanent hairwhich is economical to manufacture and Figure 3 is'a horizontal crosssection of same taken on line 33 of Figure 2.

Figure 4 is an enlarged side elevational yiew of the nozzle showing thesame applied in po ition.

Fig re 5 is a longitudinal section through the same.

The device, embodying my invention is designed to be readily connectedto any convenient airfsupply means. The discharge of the air is effectedthrough members which are not parts of the hair waving apparatus but areindependent thereof and are provided with means for readily attachingsaid members or nozzles to the means associated 65 with the hair wavingapparatus, such as felt pads generally used to protect the scalp fromthe curling rods. This arrangement enables the use of my improved devicewith any type of hair waving apparatus, thereby 7 greatly increasing therange of usefulness of my device.

In the hair waving process a portion of the hair is twisted on a curlingpin A and is held thereon by a wrapper B which is usually treated with asuitable liquid. A heating element C is then placed over thecurling pinand the hair.

In order to protect the scalp from the heat and the steam generated bythe heating of the liquid, a felt pad 10 is slipped over the saidportion of hair and placed close to thescalp and a fiber washer 11 isplaced on top of felt washer 10. This fiber washeris preferably made oftwo pieces hing'edly connected together so as to enable the positioningand removal 1 of the fiber washer without the necessity of threading thehair therethrough, thereby providing a comparatively small opening forthe reception of hair.

The above described method is the one generally used. In practice, ithas been found that a certain amount of steam or hot liquid will findits way through said washers to the scalp and cause injury to the scalp,sometimes producing total loss of hair at such spots.

My improved device comprises a tubular member 14 of suitable diameterand length.

the nozzle 19 is One end of this member is left open and has securedthereto one end of a flexible tubular coupling or connection 15, theopposite end of which is adapted to be detachably secured to thedischarge end of a suitable air blower or air supply means such as ahair drier 16. The opposite en of member 14 is closed as shown at 14 andformed in said closed end is a series of outwardly projecting tubularextensions or nipples 17 which communicate with the interior of saidmember 14 and open outwardly. Each nipple 17 receives one end of aflexible tubing 18. This tubing is of suitable length so as to allowconvenient manipulation thereof and the free end of each tubing isprovided with a flattened nozzle 19 through which the air is dischargedin a flat stream. Each nozzle 19 has arranged thereon a clamping member20, preferably spring-pressed against said nozzle and adapted to beslipped over the edge of a felt pad 10 so as to hold said nozzle andsaid end of the tubing in position on the head of the person whose hairis being treated. When thus positioned, disposed on the underside of thepad 10 and practically rests on the scalp.

The size of tubular member 14 is such as to accommodate the propernumber of nip ples 17 and supply the latter with the proper amountof'air. The number of nipples used is substantially the same as thenumber of curling pins A used with the waving ap-.

paratus so that each curling element is supcoupling 15 to thedistributor 14. From rate stand is required, my

lied. with a nozzle 19. The air discharged romthe supply means 16 isdelivered by the the latter a proper portion of air is forced througheach nipple l7 and tubing 18 to a nozzle 19 which directs the airagainst the scalp, thereby cooling the same and preventing any 'steam orhot liquid from coming in contact therewith, and causing injury thereto.

The use of my scalp cooling device does not interfere in any way withthe operation or the installation of the hair waving apparatus and doesnot affect the hair which is being treated. As said cooling device isentirely; independent of the hair waving apparatus, it may be applied inposition at any time during the hair waving treatment and may bediscontinued whenever desirable. The device is supported in position bythe hair drier 16 from which it is suspended by the flexible coupling15. As practically all of the establishments are equipped 'with hairdriers, they can adopt the use of my cooling device without any verygreat additional expense. Furthermore, as no sepadevice does not take upany floor space and can be readily put away.

' ratus,

When tubing 18 is formed of rubber, it

is preferably provided near its freeornozzle end with a heat resistantportion or covering 18 which protects the tubing from injury from heatof the hair curling devices with which it may be accidentally brought incontact. Coupling 15 is designed to provide ready means for connectingthe distributor to any convenient air supply. However, if desired thedistributor itself may be attached to such air supply means. The airdischarged from the nozzles is of sufficient quantity to cool the scalpand blow away steam or hot liquid which accidentally finds its way pastsaid washer and pad. In this manner, the scalp is effectively protectedand all danger of injury thereto is removed, making the hair wavingprocess safe and comfortable. v

While I have shown and described the preferred form of my invention,understood that the arrangement of parts itistobeand the construction ofdevice can be.
